Despite policies aimed at increasing bicycle use, and the health benefits identified in the literature, cycling mobility is still quite limited in most cities. A cultural transformation is needed to change this situation. E-bikes might be capable of triggering this change, and turning the proposition of cycling into the preferred choice for everyday mobility. To explore this possibility, the present study extends a previous analysis conducted on the representation of cycling in Italian media, and further investigates its content as regards e-bikes.

The road safety of vulnerable users is a current issue; in densely populated areas, the use of alternative and light mobility vehicles is growing in popularity, and their users conflict with vehicles having larger dimensions and masses. This study focuses on the risk analysis of collision between bicyclists and motorized vehicles in urban intersections. Twenty-five urban four-leg intersections, with and without bike paths, were considered in order to identify the conflict points, calculate their hazardousness, and assess the risk of collision using a probabilistic approach.
